Abstract
The invention relates to a discharge system having a waste-producing unit (1) (especially a vehicle toilet), a device (6) for generating underpressure, a buffer container (17) and a collection tank (9) interconnected via pipes (7, 10, 15) with valves (5, 8, 20). The device (6) evacuates to generate underpressure in the buffer container (17) or creates underpressure in it so that, with the valve (5) in the line (17) to the waste-producing unit (1) open, the waste is sucked into the buffer container (17). With the valve (20) in the compressed air feed line (15) open and the valve (5) in the line (7) to the waste-producing unit (1) closed, the waste sucked into the buffer container (17) is discharged into the collection tank (9).
Description
Discharge system for the discharge mass of a unit producing a discharge mass.
The invention refers to a discharge system with a unit producing a discharge mass (in particular a toilet basin in a vehicle), a device to create partial vacuum, an intermediate container and a collecting basin that are joined via pipelines with valves.
In a known discharge system of this type (DE-OS 39 32 893), air or the gases are removed from the collecting basin and the intermediate container and fed into a pressure vessel.
Furthermore, the pressure vessel, along with the vacuum in the intermediate container and collecting basin, ensures that the discharge mass makes its way into the collecting basin.
However, the vacuum generator and the pressure vessel cannot be sized large enough to achieve this, such that there are doubts as to whether the known system even functions. Since the collecting basin has a relatively large volume, the vacuum pump would also have to be designed fairly large. In any case, because of this large volume, the unit producing the discharge mass would only be able to be used - if at all - at relatively long intervals.
In the known system, there are also a number of devices necessary that make the entire system not only awkward and prone to trouble, but also quite costly.
The invention is based on the task of more simply designing the discharge system of the type mentioned in the beginning and also simplifying it in terms of technically required cost.
In summary this invention seeks to provide a discharge system with a unit (1) producing a discharge mass and more particularly for use with a toilet basin in a vehicle, an ejector device (6) to create partial vacuum, an intermediate container (17) and a collecting basin (9) that are joined via pipes (7, 10) with valves (5, 8), wherein the ejector device(6) ' 23267-83 210 8 2 5 7 2a to create partial vacuum puts the intermediate container (17) under partial vacuum, the discharge mass is sucked into the intermediate container (17) when the valve (5) is open in the pipe (7) from the unit (1) producing the discharge mass, and the discharge mass is pressed from there into the collecting container (9), characterized in that a valve (20) in a compressed air feed pipe (15), when it is in open position and the valve (5) in the pipe (7) to the unit (1) producing the discharge mass is closed, causes the discharge mass sucked into the intermediate container (17) to be pressed into the collecting basin (9); the intermediate container (17) has a volume of only a few liters and that all valves (5, 8, 20), the intermediate container (17), the device (6) to create partial vacuum and all pipes (7, 15) except for the pipe (10) leading to the collecting basin (9) are housed on the unit (1) producing the discharge mass or in the seat of the toilet basin.
First of all, it is significant that a relatively small vacuum-creating device can be used, since only the relatively small volume of the intermediate container, a matter of a few liters, has to be evacuated. If the intermediate container has been placed under sufficient vacuum, the discharge mass can be sucked in and, by introducing compressed air, pressed out of the intermediate container into the collecting basin. Besides the lower cost with respect to the vacuum pump, with the discharge system according to the invention the unit producing the discharge mass can be used at relatively short intervals.
According to the invention, except for the collecting basin and the pipe leading to it, all pipes, all valves as well as the intermediate container and the vacuum device are in the immediate vicinity of the toilet basin, i.e., either in the seat area or below the bowl. This is particularly significant when considering installations in vehicles in which space problems already occur.
The invention is particularly useful for rail-bound vehicles, but also for overland buses, for example.
The invention is explained with the help of the drawing.
The single figure of the drawing shows a diagram of the discharge system according to the invention.
In the figure, 1 designates a toilet basin equipped with a known flushing system (not described in detail). At the discharge end of the toilet bowl 1 there is a valve 5 that leads via a pipe 7 to an intermediate container 17 in which a vacuum device is arranged either in the immediate vicinity or via a short pipe with valve.
The vacuum device 6 is designed in such a way that the interior of the intermediate container 17 can be evacuated quickly. The gases sucked off can also be fed into the collecting basin 9. The vacuum device can also be an ejector that is activated via the already existing compressed air installation.
Furthermore, a pipe 15 leads into the collecting basin 17 via a valve 20; this pipe is connected to the compressed air network or a compressed air generator.
The drawing shows in diagram form: control pipes for the valves as well as measuring and command pipes (in solid lines) that lead to a control not shown.
If discharge mass is to be removed from the toilet bowl 1, first the actual flushing step is initiated, during which the valve 5 is closed. The vacuum pump 6 has already evacuated the interior of the intermediate container 17 beforehand, and the valves 20 and 8 are closed.
Next, valve 5 is opened in such a way that the discharge mass makes its way as a result of the partial vacuum via the pipe 7 into the intermediate container 17.
Then, the valve 5 is closed and valves 8 and 20 are opened, in such a way that the compressed air presses the discharge mass out of the intermediate container 17 into the collecting basin.
The collecting basin 9 can have a volume of 100 liters or more. On the other hand, the intermediate container 17 can have a content of a few liters, for example. Only Fractions o a liter of flush water are needed for the flushing step itself in the discharge system according to the invention.
In the preferred form of construction of the present invention, it is useful to use the compressed air system already existing in rail vehicles, where a pump with mechanically moving parts is not required, but rather an ejector can be used. This means that instead of mechanical pumps, only valves are needed. In addition, the on-board electrical system of rail-bound vehicles provides a relatively high pressure in such a way that on the one hand, the desired high vacuum output is possible and, on the other hand, the conveying step of the produced discharge mass from the intermediate container into the discharge container can be carried out reliably. Finally, there is the fact that relatively little flushing water is needed, which is particularly significant in the case of frost-endangered spaces.
